07 Dodge Nitro RT 4.0
I have an 07 Dodge Nitro RT 4.0. The other day I had the water pump replaced and it costs $560 They did not change my timing belt the next day my car lost power and now I can't get it turned over. I had someone hook it up to the computer and it said it was the timing belt. Should that have been changed at the same time and can I go back to the dealership and have them change it Free of charge? The mechanic told me he had taken it off and put it right back on.
